## Bitfinex Honey Framework Trading Strategy Live Execution Module for Node.JS

[![Build Status](https://travis-ci.org/bitfinexcom/bfx-hf-strategy-exec.svg?branch=master)](https://travis-ci.org/bitfinexcom/bfx-hf-strategy-exec)

This module can execute strategies built with `bfx-hf-strategy` on a live data stream from Bitfinex via v2 of the WS API. Strategy indicators are initially seeded with the last 1000 candles by default, but this is configurably with the `seedCandleCount` argument. Trade data can be included on the stream by passing `includeTrades: true` when calling `exec()`.

### Features

* Cross-compatible with `bfx-hf-backtest` allowing the same strategy to be both backtested and executed seamlessly
* Execute trading strategies on the live Bitfinex markets
* Utilizes a multiplexing websocket connection manager to scale with channel subscriptions

### Installation

```bash
npm i --save bfx-hf-strategy-exec
```

### Quickstart & Example
```js
const { SYMBOLS, TIME_FRAMES } = require('bfx-hf-util')
const { RESTv2 } = require('bfx-api-node-rest')
const { Manager } = require('bfx-api-node-core')
const LiveStrategyExecution = require('bfx-hf-stratey-exec')
const CustomTradingStrategy = require('./somewhere')

const ws2Manager = new Manager({ /*...*/ }) // see bfx-api-node-core docs
const strategy = await CustomTradingStrategy({ /* optionally pass args */ })

const rest = new RESTv2({
url: 'https://api.bitfinex.com',
transform: true
})

ws2Manager.onceWS('event:auth:success', {}, async (authEvent, ws) => {
strategy.ws = ws

const strategyOpts = {
symbol: SYMBOLS.EOS_USD, // data stream symbol
tf: TIME_FRAMES.ONE_DAY, // candle data stream time frame
includeTrades: true,
seedCandleCount: 5000 // indicator candle seed window
}

const liveExecutor = new LiveStrategyExecution({ strategy, ws2Manager, rest, strategyOpts })

liveExecutor.on('error', (err) => {
// handle errors
console.error(err)
})

await liveExecutor.execute()
})

ws2Manager.openWS()
```

#### Reconnections

Please note that the connection is handled by the `bfx-api-node-core` websocket manager. For a full example that uses the Watchdog Plugin, take a look at the [example](/examples/exec.js)
